title: Wound infection rate and irrigation pressure of two potential new wound irrigation devices: the port and the cap.
abstract: The objectives of this study were to determine the speed of irrigation and the infection rate of two new irrigation devices. In the clinical portion of this two-part study, 208 patients with traumatic wounds were randomized to one of two new irrigation device groups, the cap/bottle or the port/bag, to determine irrigation times and infection/complication rates. Wounds were irrigated in less than 4 minutes in 97% of patients using a mean of 786 mL. The combined infection/complication rates were: port group, 1 of 99 (1%); cap group, 4 of 108 (4%), P = .356. In part II, 9 male and 8 female medical volunteers were timed in the delivery of 250 mL of saline into a graduated cylinder, using four different irrigation set-ups. Mean time for 250 mL and calculated stream pressures (psi) were: (1) cap/bottle, 12.9 seconds, 1.5 psi; (2) port/bag, 11.2 seconds, 2.0 psi; (3) syringe/catheter, 113.2 seconds, 8.2 psi; and (4) syringe/needle, 175.4 seconds, 7.3 psi (time and psi: P < .05 for all pairwise comparisons except cap versus port). Rapid irrigation and infection rates comparable with standard devices used in wound irrigation suggest that the new devices may prove to be valuable tools in emergent wound care.
